I found all the parts of the lifter in the lifter gallery except for the metering disc from the lifter. I had to pull the whole motor out to find that one small stupid disc. If screens were in there, it would have caught the disc. I run hydraulic flat tappet lifters so no worries about and roller wheels breaking. As far as the video of dumping oil into the lifter gallery goes, I say it is misleading. The top end of your motor does not flow that much oil. have you ever seen the very small stream of oil running back to the block at idle, high RPM would be considerably more, but not that much, and the video was with cold oil.
